Between two on-premises VMM sites

1. Download the latest Update Rollup for Microsoft Azure Site Recovery Provider.
2. Install the Update Rollup first on the on-premises VMM server that's managing the recovery site.
3. After the recovery site is updated, install the Update Rollup on the VMM server that's managing the primary site.

Note If the VMM is a Highly Available VMM (Clustered VMM), make sure that you install the upgrade on all nodes of the cluster where the VMM service is installed.
 

Between an on-premises VMM site and Azure

1. Download the Update Rollup for Microsoft Azure Site Recovery Provider.
2. Install the Update Rollup on the on-premises VMM server.
3. Install the latest MARS agent on all Hyper-V hosts.

Note If your VMM is a Highly Available VMM (Clustered VMM), make sure that you install the upgrade on all nodes of the cluster where the VMM service is installed.
 

Between an on-premises Hyper-V site and Azure

1. Download the Update Rollup for Microsoft Azure Site Recovery Provider.
2. Install the provider on each node of the Hyper-V servers that you have registered in Azure Site Recovery.

Note If your Hyper-V is a Host Clustered Hyper-V server, make sure that you install the upgrade on all nodes of the cluster.
 

Between an on-premises VMware or physical site to Azure

1. Update your on-premises management server by downloading Microsoft Azure Site Recovery Provider Unified Setup. This is the server that has the Configuration server and Process server roles.
2. If you have scale-out process servers, update them next by running Microsoft Azure Site Recovery Provider Unified Setup.
3. Go to the Azure portal, and then go to the Protected Items > Replicated Items page. Select a VM on this page. Select the Update Agent button that appears at the bottom of the page for each VM. This updates the Mobility Service Agent on all protected VMs.

Note A restart is recommended after every upgrade of the Mobility agent to make sure that all latest changes are loaded on the source computer. This is not necessarily mandatory. However, a restart is mandatory if the difference between agent versions from the last restart and the target version is greater than four (4) in the last decimal place. See the following table for a detailed explanation.
